Roth IRA Conversion Calculator to Calculate Retirement Comparisons

Roth IRA Conversion Calculator Sign

This calculator will help you to compare the net effects of keeping your traditional Individual Retirement Account versus converting it to a Roth IRA.

Not only will the calculator show you the forecasted monthly and annual retirement income for both scenarios, but will also compare the two scenarios before, at, and during your retirement.

And finally, the calculated results also include a button for creating a printer-friendly report.

Note that if you're not sure what a Traditional IRA is, or what a Roth IRA is, or what their respective advantages, disadvantages, and purposes are, please visit the Roth Vs Traditional IRA Calculator.

Important: All calculated results are hypothetical, so be sure to consult a qualified tax professional before making any decisions concerning your IRAs.

When you convert your standard IRA to a Roth IRA, the portion of your IRA that is deductible will be added to your taxable income for the current year. This means you will need to come up with funds to pay taxes on that additional income. If you plan to pay the conversion taxes out of non-IRA assets (savings account, cash, etc.), choose non-IRA assets. If you plan to pay the taxes from your IRA (thereby reducing the value of your IRA) choose IRA proceeds.

Notes

Things to keep in mind when using the calculator.

Crystal Ball Predictions

While researching the information needed to build this calculator, one thing became clear -- no two Roth IRA calculators contain the same entry fields -- much less generate the same results.

The reasons for this phenomenon probably stem from the fact that they are all making crystal ball assumptions and predictions.

Can You See Into the Future?

To forecast the exact comparative consequences of converting your traditional IRA to a Roth IRA, you would need to be able to make precise predictions about the following details the calculators depend on for the calculations:

  • Precisely when you will retire and how long you will live.
  • Your specific state and federal tax bracket during each remaining year of your life.
  • All changes to tax laws between now and when you die.
  • How much you will need to withdraw from your retirement account each year of your retirement.

Well, since few of us even know for certain what tomorrow will bring, making predictions about the state of our health, wealth and tax laws years into the future is probably not a good investment of your time.

However, what is a good investment of your time, is taking the time to learn what an Individual Retirement Account (IRA) is, what a Roth IRA is, their advantages and disadvantages, and how they compare to other retirement investment options.

Saving for Retirement is Only Half the Equation

While contemplating contributing to an IRA or converting to a Roth IRA, be sure to keep in mind that investing and saving for retirement is only half the equation.

After all, if you have a mountain of debt on the day you retire, the proceeds from your retirement investment funds will have to go toward paying bills instead of paying for airfare to remote, tropical beaches.

Therefore your retirement might be better served by using extra money for paying off high interest debt (Invest in Your Debt Calculator).

Just the Honest Basics Please

While I'm by no means an expert in retirement investment options, I do have one important quality that should make what I have to say worth reading:

I'm not trying to sell you an IRA -- traditional, Roth or otherwise.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
